Students collect constant velocity data and plug it in to Excel. Excel then graphs the data, and students use the Companion Document to answer analysis questions. .
If there are air leaks in a house, you might expect that their effect would be magnified on a windy day. The wind creates greater air pressure on the windward side of the building and forces air in through the leaks. At the same time, the pressure on the other side of the building is lowered, pulling air out through leaks. This model has a fan blowing against a building. Air motion is shown with arrows. Open and close the "windows" in the building and observe the results.
Convection refers to transfer of heat by a fluid material (such as air or water) moving from one place to another. The convection is forced if the fluid motion is caused by a fan or a pump while natural convection is the result of density differences.
Conduction of heat refers to the transfer of heat through a solid. Convection refers to the transfer of heat by a fluid material (such as air or water) moving from one place to another. Warm air is less dense than cold air, so it rises and cold air sinks. This is called natural convection. Air is constantly circulating indoors and outdoors, moving heat from one place to another. With this model you can compare how conduction and convection transfer heat.
The convection of heat in air happens naturally because warmer air is less dense and rises, causing air circulation in many situations. But not always! Air can stratify, with warmer air up high and cooler air down low. With this model you can explore how convection works if the heat source is near the ceiling of a room. You can also compare it to conduction in the same setting.
Air circulates quickly and easily if there are temperature differences to drive its motion. This may be desirable in a room, but in insulated walls and ceilings air circulation is a problem, since it transfers heat. Explore the effect of multiple barriers on the amount of convection and apply this to how insulation should be designed.
Most buildings have leaky places where air can enter or escape -- around windows, ceiling openings like pipes, wires or chimneys, and construction joints such as where the wall meets the floor or the floor rests on the foundation. The size and location of these leaks strongly affects the heating and cooling load. Use this model to experiment with wall and roof leaks in a house with a heater where the air can circulate freely.
Explore how potential energy created by particles of varying charge is converted to thermal energy.
Energy is continuously transferred from one place to another and transformed among various forms. In this lesson students will learn and demonstrate how energy is transferred from one form to another through various sequences. Additionally, they will explore binary code and how it can be converted from one form into another and transferred from one object to another.
This is a set of three, one-page problems about how astronomers use coordinate systems. Learners will plot a constellation on a coordinate plane and/or plot the route of Mars Science Lab (MSL aka Curiosity) on the surface of Mars. Options are presented so that students may learn about the MSL mission through a NASA press release or about the coordinate plane by viewing a NASA eClips video [7 min.]. This activity is part of the Space Math multi-media modules that integrate NASA press releases, NASA archival video, and mathematics problems targeted at specific math standards commonly encountered in middle school.
Visualize the electrostatic force that two charges exert on each other. Observe how changing the sign and magnitude of the charges and the distance between them affects the electrostatic force.

Adam Seipel, with VaSCL (Virginia School Consortium for Learning), provides this recorded presentation and slide deck for creating a learning community with your students who are at home using Google Meet and Flipgrid.
In this lesson, students create a compass and apply their reasoning about magnetism to how compasses work to help us navigate around the globe while utilizing the Earth���s magnetic field.
Experiment with a simulated Crookes tube for qualitative results similar to Thomson's experiments in which the electron was discovered.
This activity aims to engage middle-school students with cyberbiosecurity topics through a murder mystery-style puzzle. As the narrator, you will set the cybercrime scene and provide breadcrumbs along the way. Your students will serve as investigators, drawing connections between agricultural and computer science topics while they solve the crime. This activity is part of the Agricultural Cyberbiosecurity Education Resource Collection that contains resources for formal and non-formal agricultural educators working with middle school aged youth. Published as Open Educational Resources, all resources are provided in durable (pdf) and customizable (MS Word) formats. They are hosted on GoOpenVA in a unique resource collection, Ag Cybersecurity Virginia Tech, at https://goopenva.org/curated-collections/143 and on on Virginia Tech’s stable repository, VTechWorks at https://doi.org/10.21061/cyberbiosecurityThis work is supported by the USDA National Institute of Food and Agriculture, Women and Minorities in Science, Technology, Engineering, and Mathematics Fields (WAMS) Grants Program, award #2020-38503-31950.

Students will use predetermined materials to create prototypes of badge covers to try to block RFID signals from being read.
El módulo de Clima de High-Adventure Science tiene cinco actividades. El módulo explora la pregunta, "¿Cómo será el clima de la Tierra en el futuro?" A través de una serie de preguntas guiadas, explorarás las interacciones entre los factores que afectan el clima de la Tierra. Explora los datos de temperatura de núcleos de hielo, sedimentos y satélites, y los datos de gases de efecto invernadero de las mediciones atmosféricas, realiza experimentos con modelos computacionales y escucha de un científico del clima que trabaja para responder la misma pregunta. No podrás contestar la pregunta al final del módulo, pero podrás explicar cómo los científicos están seguros de que la Tierra se está calentando sin tener la certeza absoluta de cuánto se calentará.
